The innovative PEEK self-punching anchor, including both medial row and lateral anchors.
includes PEEK sheath and PEEK interface screws, which can achieve 360-degree wall contact of the tendon with the sheath and screws, increasing the contact area between the tendon and bone, thereby improving the tendon-bone healing efficiency.
Interface screws are widely used implants in sports medicine surgeries, commonly used in knee joint cruciate ligament, ankle joint tendon, and other limb tendon ligament reconstruction surgeries, to fix autologous tendons, ligaments, or autologous ligament grafts into bone tunnels, achieving a firm connection between soft tissue and bone. Tendon-ligament fixation screws made of polyether ether ketone (PEEK) material have high mechanical strength, an elastic modulus similar to that of bone, and excellent friction performance, reducing the cutting of tendons or grafts during insertion compared to metal interface screws.
